Luke Martino, Non-Executive Chairman of the Board, said “ The geochemical results of detailed sampling and geophysical data have demonstrated the validity of the exploration process and have greatly aided the understanding of the basin and indicating the potential of Vranje-South project to host Li – B mineralisation. The assay results from detailed sampling and geophysics data will aid in defining drilling targets to test defined anomalies. ”

Jadar Lithium Limited (ASX: JDR) (“Jadar” or “the Company”) is pleased to provide an update on detailed sampling; acquisition and interpretation of regional gravity and magnetic survey data on the Vranje-South project in Serbia.
The objective of the latest field program was to determine the geometry of the sedimentary basin within the permit and to understand the sedimentary sequences which are associated with the elevated Lithium and Boron geochemical anomalies in more detail.

Rekovac (100% interest - ~75.4km[2] )
Vranje-South (100% interest - ~90.44km[2] )
The field mapping and detailed sampling program focused on exposed sedimentary formations in an attempt to locate outcropping fine pelitic strata which are known to be favorable hosts for Li-B mineralisation. The samples were sent to the ALS laboratory in Bor, Serbia, where the samples were prepared and then forwarded to the ALS laboratory in Ireland for analysis of Lithium, Boron and associated elements.
The Company also acquired regional gravity and magnetic survey data from a local contractor who re-interpreted the data with the aim to outline underlying basin geometry and define the presence Calc-Alkaline volcanism that may be a source of mineral-bearing fluids.
With the conclusion of the above program, the Company is aiming to execute a scout drilling campaign in the near future.
Sampling
In total, 28 rock samples were collected and dispatched for geochemical analyses. The assays returned with elevated Li and B values with up to 430 ppm of boron and up to 180 ppm of lithium. The assay data also showed elevated As, Mg and K values which are indicative elements of an alkaline saline depositional environment. This suggests that the basin contains permissive sediments that may host deposits of stratabound ores of chemical precipitates.

During the sampling program, the Company identified the presence of numerous efflorescence, a “wooly” appearance of fine white fibers within the project area. XRD analyses of sampled efflorescence returned with two detected evaporate minerals in the sample, Hexahydrite (MgSO4.6H2O) and Gypsum (CaSO4.2H2O).

Presence of those two minerals within the sedimentary basin is encouraging as it is suggesting that the depositional environment was alkaline saline. This is considered permissive for stratabound Lithium-Borate deposit.
Gravity Survey
The Company acquired regional gravity survey data from the local contractor “Vecom GEO doo”. This data was acquired to aid in defining basin geometry and deep-seated fault zones, which may have acted as a potential conduit for mineralizing fluids. The data has been combined with the surface sampling data and used to assist in defining drilling targets. The gravity method is a useful exploration tool to visualize the basin geometry and relative thickness of the sedimentary section through defining basin highs and lows. The gravity surveys were accomplished as grids with nominal station spacing of approximately 1000m.
The Vranje basin has an elongated shape demonstrating a north-south trend that parallels the regional tectonic Paleozoic extensional structures. Based upon the linear configuration, the sharp parallel gradients on both the north and the south sides and deep gravity low (blue) suggest parallel faulting of basement rocks formed the basin.
Sedimentation in the Vranje basin is composed of extensive lacustrine sediments. Due to the long trough geometry and steep, probably faulted flanks, it likely contains some components of interbedded clastic (sands). The overall grain size suggests quiet water deposition. Since it contains such a well-defined gravity closure from at least - 34.0 to - 42.0 mGal, there is almost certainly an early period of lacustrine sedimentary deposition when the basin was isolated from drainage.

Regional Magnetic Survey
The ground magnetic survey has been acquired to aid in defining the presence of “blind” (covered by hangingwall sediments) Calc – Alkaline volcanic formations that may be related to a spring emanation. The spring waters likely dispersed their elements broadly into the lake waters and only upon reaching appropriate cooling, pH and redox conditions provided favorable conditions for evaporate precipitation. The magnetic surveys were accomplished as grids with station spacing approximately at about 2000m.

Vranje South Project Geology
Most of the exposed units within the license area are mapped as lake sediments consisting siltstone, claystone, coarse clastics, and volcanoclastic sediments and within the southeast corner the Paleozoic crystalline complex. The sedimentary units are sub-divided into four different sedimentary subsequences starting with volcanoclastic flows composed of andesite agglomerates, volcanic breccias, and tuffs discordantly overlaying the basement rocks. Volcanoclastic sediments overlaid by fluvial coarse clastic sediments composed of poorly sorted fanglomerates. The clastic sequences are exposed in the eastern part of the license area and represent the basal formation of fine pelitic strata which are exposed in the central and eastern portion of licenses. Pelitic sediments are represented by fine laminated to bedded clayey siltstone to laminated to bedded fine-grained sandstone. The youngest sediments mostly sandstones and siltstones are exposed in the western and northern portion of the license hiding perspective fine pelitic lake strata. The basement rocks are surrounding the Vranje basin have been mapped as various metamorphic Paleozoic rocks and older granitic intrusive.
About Vardar Zone
Pelitic sediments accumulated in several semi-interconnected basins along a geological trend that is now called the Vardar Zone (Figure 10). The Vardar Zone stretches from northern Iran to Bosnia and Herzegovina, where it appears to disappear at the edge of the Alpine formations. Basins along the long, narrow trend vary greatly in size, shape, and sedimentation. The Vardar zone was formed by the movement between two tectonic plate boundaries. This tectonic forces result in rhomboid-shaped - "pull apart" - basins between the more stable basin boundaries. The basins of interest are mapped as lacustrine and marine sediments.
Evaporate (Lithium – borate) deposits of the type being explored in Vardar zone are typically found in tectonically active zones associated with deep-seated faulting. The deposits occur in shallow water lacustrine and mudflat environments, usually accompanied by Calc - alkaline volcanics and tuffs.
In the Balkan region, borate and lithium mineral deposits and occurrences have been recognized in recent years. These occurrences have been barely tested, while lithium mineralisation was found associated with borates even more recently during drilling in the Jadar basin of Serbia. Beside Jadar deposit which is the world´s largest lithium - borate deposit, borates have been found in Pobrdje and Piskanja within the Jarandol deposit. Some of the world´s largest borate deposits were discovered as well within the Vardar zone. Kirka borax deposit in Turkey is the world´s largest deposit and it´s located central part of Vardar trend.
